'VEHICLE-"WHEEL Application filed April 30, 1912.

To all whom t may concern.'

Be it known that l, ERLn K. BAKER, a citizen of the-United States, and a resident of Chicago,v Cook county, Illinois. have invented certain new and useful lmprovements in Vehicle-VVheels, of .which the following is a specification. j

My invention lrelates to improvements in vehicle wheels and has particular reference to improvements in demountable rims for resilient tires. I

The object of my invention is to provide a demountable rim of simple construction which shall be capable of being easily and quickly placed upon and taken from av resilient tire, which has a base that is substan tia-lly inexpansible.

My invention resides in a tire rim pro vided with a relatively short removable section which is permanently attached or hinged to one end of the rim and is adapted to be removably Yor detacliably connected with the opposite end of the rim.

My invention further includes the idea of providing a relatively large opening or hole in this removable part through which the valve stem of the tire may be projected and ywhich may be made use of in combination with a suitably shaped tool toeffect the contraction of the rim.

My invention also includes the idea ofv making an easily collapsible rim which is provided with integrally anged edges and.

which is adapted to carry or retain either 1t two types of tires.

My invention also consists in the various features of construction and the several combinations of parts whereby `and wherein the aboveand other ideas are embodied and all :as-.hereinafter described a'iid .particularly pointed out in the appended claims.

My invention will be more readily understood by reference to the accompanying dra-wings forming part of this specification and in which:

Figure 1 is a side elevation, partly in section, of a vehicle wheel equipped with a pneumatic tire and made in accordance with my invention; F 2 is an enlarged sectional view similar to .the sectional part shown in -Fig '1, the tire being removed; Fig. 3 is a side elevation of the rim shown in its contracted condition; Fig. l is an enlarged inner View of the rim showing the removable section; Figs. 5, 6, 7 and 8 are trans specification of Letters raient.

verse sectionsot the rim of the wheel showing the wheel equipped with different forms of rims adapted to receive and hold various types of tires; Fig. 9 is side elevation of .the contracting tool; Figi() is an end view of the contracting tool; and Fig. 1l is an enlarged view of one of the dowel pins.

The wheel. whichv l have illustrated is formed in the usual manner, and consists of ahub 2,` spokes 3 and telly d. llnhe'felly is equipped witlrav continuous metal ring or` telly band 5 which ispermanently mounted thereon: This telly band is substantially cylindrical in form and is provided at its rear edge with acontinuous circumferential flange 6 which projects outwardly at an angle and is adapted to support one side or edge of the tire rim 7. The opposite edge of the tire rim is adaptedto be supported upon wedging lugs 8 which are carried upon transversely mounted screw bolts 9, and the telly is provided with fixed nuts l0, the cooperation of the bolts and nuts being adapted to draw` the wedges between the tire rim 7 and the felly band 5 and removably but rigidly secure the tire rim upon the wheel.

The tire rim is substantially 'channelshaped in cross sect ion,' that is, it has a substantially cylindricalmiddle or base por' tion, l1, which is bordered by integral outwardly extending flanges lf2 at each edge. These flanges may "take several forms, that is, they may be formed to adapt the rim to receive and hold \ditl"erent types of rims. For instance,-in Fig. 5 l have shown the rim adapted to receive ndiat is known "as a straight side or Dunlop form of tire, -the lianges in this case extending radially out- `ward substantially at right angles to the ebase 'portion of the rim. ln Fig. 6 l ,have shown the flanges' 12 as being curved or turned inwardly, forming hooked flanges,

In Fig. 7 I have illustrated v The opposite flange ,is turned inwardly to form a hooked flange to 'receive a clencher tire and the tire is provided with a loose ring, similar to the ring 13, which is formed radially on one surface to coact'. with the Dunlop Harige and hooked on its opposite surface to coact with the clencher flange to adapt the rim for receiving either a Dunlop tire or a olencher tire.r In all cases the rim is `formed of a main circumterential part or section 15 and a relatively small part or section 16. ln the production of these rims l usually roll them in the form of an endless ring and then cut the rim at two transverse points to formthe two parts or y sections of' the rim. The small or removable section of the rim 1G is mounted upon or riveted to a bridge plate 17 which is conformed to and contacts with the inneisurface of the rim and hes in the space between the rim and the felly band. One end 1S of this bridge plate coincides with one endof the small section 16 and the plate is formed at this end to be pivotally mounted upon a hinge member 19 secured to the adjacent end 2O 'of the main part of the rim. The pivot 21 of' the hinge is located immediately within the adjacent joint formed between the removable section and the end Q0 of the rim, and the removable section is" adapted to be rotated on the hinge joint and thus be withdrawn inwardly from its normal position. rlihe oint 23 between the opposite end of the section and the opposite end 24 of the main part of the rim is cut on such an angle that the small section can be removed by rotation plate 17 is riveted to the removable section by rivets which have large heads 26 on their inner ends, said heads being adapted to project into sockets 27 provided in the telly of the wheel and thereby retain the rim and wheel against relative movement. The bridge'plate, as explained before, extends beyond ythe removable section and projects beneath the opposite end Q4 of the main part ofthe rim, and4 is provided with holes 28 adapted to receive dowel pins 2S) which project inwardlyfrom the inner surface of the main Dart of the rim. These. dowels 2S) are similar to the headsfi of the rivets 25 and are adapted to enter sockets formed in the rim *similar to the sockets Q7. Each of these. dowels 29 is provided with an annular groove 30 adjacent to its base.` the purpose of' which will be described hereinafter. The end 2i of the main part of the rim is provided Withfa notch or` opening 3l adapted to able valvestem opening 34. For the purposev of contracting Athe rim suicie'ntly either to place the extra flange 13 thereon,V

or for the purpose of placing the rim upon a tire or removing it therefrom, l provide a tool 35 which is formed at one end 36 to be useful as a tire tool and at the other end is formed into a hook 37 which is adapted toy project into one of the grooves 30 when the tool is placed against the dowel pin. This tool is used in the mannerclearly illustrated vbridge plate and then the hooked end of the tool is passed through the valve stem hole and placed against one of the dowel pins, the booked end of the tool entering the groove 30 of the pin and forming a reliablef tulcrum. The other end of the tool is then forced transversely in a direction to lcontract the rim` as shown in Fig. 3.

The rim as herein described is one which can be manufactured at a relatively low cost. it can be easily manipulated to place it upon or remove it from a resilient tire which has a substantially inexpansible base and in itself separate from the wheel upon which it is intended to be used, it forms a complete tire carrier adapted to carry a pneumatic tire in inflated condition ready foriimmediate application to a wheel.

:is many further modifications of my invention will readily suggest .themselves to one skilled in the art, l do not limit or confine myself to the specific structures herein shown and described.

Having thus'described my invention` l claim as new and desire to secure bv lietters Patent: I
